set the 16-bit start address (i.e., byte access). In a 16-bit memory configuration these are the 16 most sig-
nificant bits of a 17-bit start address (i.e., word access).
In a dual panel configuration, screen 2 refers to the lower half of the display. The Screen 2 Display Start
Address is the memory address corresponding to the first displayed pixel in the first line of the lower half
of the display. If screen 2 is started right after screen 1, the screen 2 display start address can be calculated

In a single panel configuration, screen 2 refers to the second screen of the Split Screen Display Feature
where two different images (screen 1 and screen 2) can be displayed at the same time on one display. The
Screen 2 Display Start Address is the memory address corresponding to the first pixel of the second image
stored in display memory. To display screen 2 refer to AUX[0A] Screen 1 Display Line Count Register
